I don't know what part of Canada you are in, but it is going to be 15C tomorrow here in Calgary!
As for these books on hell, I had a very vivid and scary vision of hell, when I was on LSD once when I was a teenager. Sadly, it didn't move me at all towards God. It was like, I knew hell was real, the vision was probably similar to hell, (or I really saw hell!) but, it had no power over me. Or, perhaps the devil had me in his grip at that time, and didn't need to do anything.
I needed to hear about the love of God, through many people, including reading the Bible before God reached a point in softening my hard heart enough to save me.
I suppose there is the carrot and the stick. I had just never heard of anyone getting saved because God gave them a vision of hell.
